Abstract: ABSTRACT     A fluid controlled and regulated apparatus that has a continuous input signal of variable pressure, a continuous input supply of constant pressure, and a pulsating output signal of variable pressure, that is particularly adapted for, but not limited to, the introduction of odorants into a gas supply system to aid in detecting leaks therein.  The apparatus measures the volume of natural gas flowing in a pipeline and converts that measurement into the input signal which controls a plurality of interconnected fluid piston valves to convert the input supply into the output signal.  The output signal drives a reciprocating pump in a chemical injector system, which injects an odorant into the natural gas flowing in a pipeline.

Abstract: A control device for a storage battery consists of a charge regulating loop including a circuit for supply clock pulses having a variable frequency proportional to a battery charge and discharge current, a circuit for estimating an instantaneous capacity of the battery depending on a clock pulse up-down count, and a regulating circuit for recharging the battery from a mains voltage as soon as the instantaneous capacity is equal to a first capacity (90%) substantially less than a maximum capacity of the battery. According to the invention, the frequency of the clock pulses depends also on at least one of the parameters relating to an energy efficiency of the battery and to a self-discharge current of the battery, so that these parameters are involved in estimating the instantaneous capacity. Also, the device gives warning, through an alarm, that the battery voltage is considerably more than a discharge threshold which, when reached, disconnects the battery from a load circuit. The end of battery life determined depending on charge and discharge cycles and battery aging is also signaled.

Abstract: ABSTRACT OF THE DISCLOSURE        A luminescence detecting device including a luminescence sensitive member made of a transparent resin or the like and containing at least two different kinds of organic phosphors dispersed therein.  The first organic phosphor is operative to absorb fluorescence from incident radiation such as the index phosphor stripes from a reflex color cathode ray tube, and has a response spectrum which overlaps with the wavelength range of the incident fluorescence.  The first phosphor is designed to emit fluorescence in a higher wavelength range upon excitation by the incident fluorescent radiation.  The second phosphor is responsive to the fluorescence emitted by the first phosphor since the spectra of the two phosphors overlap.  The second type of organic phosphor emits its own range of fluorescence in a particular wave band and can be detected by a luminescence sensing portion of the device to provide a signal which can be used to control the operation of the cathode ray tube.

Abstract: ABSTRACT          Some utensils have been developped and used to drain liquids off canned food from their original container.  A common and simple canned food drainer is known to be a perforated plate, a grille or grid, either fitting in the opening of a can or held in position (by locking or not) on the rim of the opened end of the can.  This invention consist of two plates, one on top of the other, sized to fit in the aperture of the can and joined together by a number of spacers.  The top plate may have at least one notch on one side or end and the bottom plate is perforated.  The device may be used to compress the food still in the can thus allowing the liquid to flow between the plates and be poured out of the can by passing trough the notch.          The operation of draining a can of food may be, by using this invention, cleaner, faster and more efficacious than using common drainers.
